Remove old spfile

You may want to remove the old spfile so that no one uses it by mistake. Use the “asmcmd rm” command to remove the old spfile.

$ asmcmd rm +DATA/asm/asmparameterfile/registry.253.715881237

NOTE: The ASM instance has to be restarted for this change to take effect. In a cluster environment, all ASM instances in the cluster have to be restarted and that can be done in a rolling fashion – one ASM instance at the time.
